Is this trial a fit for you?

Likely a good fit

Adults aged 18-60 with elevated psychopathic traits, IQ 80 or higher, and stable or no psychiatric medications for at least 4 weeks.

Probably not a fit

Individuals with certain neurological or psychiatric conditions, MRI contraindications, or significant baseline abnormalities may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized, sham-controlled study, participants with elevated psychopathic traits will receive three sessions of targeted theta burst stimulation (cTBS to the right dlPFC, iTBS to the right TPJ, or sham). Participants will undergo baseline and post-intervention MRI scans and complete assessments of social cognition and cognitive processing to see if TMS can influence brain networks and behavior. Stimulation targets are individualized using each participant’s neuroimaging data, and safety/feasibility will be monitored throughout. The trial aims to clarify whether noninvasive brain stimulation can modulate neural circuits linked to social and cognitive functioning in this population.

Why it matters

Potential benefit: If successful, the approach could lead to new tools to support social cognition and cognitive processing in people with elevated psychopathic traits.

How similar studies have gone: Previous neuromodulation studies have shown that targeted TMS can modulate cognitive and social processes in other populations, supporting exploration in this group.
